Are vacuum integrated photovoltaic curtain walls performance-driven?
The vacuum integrated photovoltaic (VPV) curtain wall has garnered widespread attention from scholars owing to its remarkable thermal insulation performance and power generation ability. However, there is a lack of in-depth, performance-driven optimal design that considers the mutually constraining functions of the VPV curtain wall.
Do VPV curtain walls save energy?
According to the literature review, VPV curtain walls exhibit significant potential for energy savings owing to their excellent thermal insulation performance . Furthermore, the shading effect of PV cells can alleviate discomfort glare and enhance occupants’ visual comfort .
Do VPV curtain walls block solar radiation?
In contrast, VPV curtain walls with high PV coverage may block large amounts of solar radiation entering the room, increasing energy consumption for lighting and heating. Thus, the single-objective optimal design of the VPV curtain walls is unable to balance its restrictive and even contradictory functions.
Are VPV curtain walls mutually constraining?
However, there is a lack of in-depth, performance-driven optimal design that considers the mutually constraining functions of the VPV curtain wall. To address this issue, this study proposed a multi-function partitioned design method for VPV curtain walls aimed at reconciling the competing demand of different functions.
Can partitioned design improve the performance of VPV curtain wall?
In summary, partitioned design method of the VPV curtain wall can improve the performance of the conventional VPV curtain wall with the same overall PV coverage. Fig. 17. Comparison of VPV windows with different PV cells distributions of coverage of 40%. 3.3.2. The optimal case obtained using TOPSIS
